Peña Boulder is a bouldering area in Idaho's Salmon-Challis National Forest, within the Salmon-Cobalt Ranger District. The Forest Service manages the land. The area is a cluster of five bouldering routes, all rated between V3 and V6-7 on the V scale. Long Boy is the easiest at V3, and Camel's Back is the hardest at V6-7. Little Ninja, Little Peña and Thick-Neck round out the set. Summer is the most comfortable time to visit. Typical averages from a nearby weather station in Salmon show July highs around 86°F with lows near 52°F, and September highs around 74°F. That station sits about 1,300 feet below the boulders, so temperatures here run cooler. Morgan Bar Campground and Wallace Lake Campground are both about 3 to 4 miles away. Salmon Idaho Bouldering is roughly 4.5 miles off, and the U P Lake hike is about 2 miles away.
